2. 6 CTLC pin input voltage "H" (VCTLCH), CTLC pin input voltage "L" (VCTLCL)

The CTLC pin input voltage "L" (VCTLCL) is the CTLC pin's voltage; when the COP pin's voltage is set to "L" after

decreasing the CTLC pin's voltage gradually from the initial status. After that, increasing the CTLC pin's voltage

gradually, the CTLC pin's voltage when the COP pin's voltage is set to "H"; is the CTLC pin input voltage "H"

(VCTLCH).

2. 7 CTLD pin input voltage "H" (VCTLDH), CTLD pin input voltage "L" (VCTLDL)

The CTLD pin input voltage "L" (VCTLDL) is the CTLD pin's voltage; when the DOP pin's voltage is set to "L" after

decreasing the CTLD pin's voltage gradually from the initial status. After that, increasing the CTLD pin's voltage

gradually, the CTLD pin's voltage when the DOP pin's voltage is set to "H"; is the CTLD pin input voltage "H"

(VCTLDH).

2. 8 SEL pin input voltage "H" (VSELH), SEL pin input voltage "L" (VSELL)

Start from the initial status, set V4 = 0 V. Confirm the DOP pin is in "L". After that, decreasing the SEL pin's

voltage gradually, the SEL pin's voltage when the DOP pin's voltage is set to "H"; is the SEL pin input voltage "L"

(VSELL). After that, increasing the SEL pin's voltage gradually, the SEL pin's voltage when the DOP pin's voltage is

set to "L"; is the SEL pin input voltage "H" (VSELH).

3. CCT pin internal resistance, CDT pin internal resistance, CIT pin internal resistance 1, CIT pin

internal resistance 2, CCT pin detection voltage, CDT pin detection voltage, CIT pin detection

voltage, load short-circuit detection delay time

(Test circuit 3)

Confirm both the COP pin and the DOP pin are in "H" (its voltage level is VDS

× 0.9 V or more) after setting VVMP =

VSEL = VCTLC = VCTLD = VDD, VVINI = CCT = CDT = CIT = VSS, V1 = V2 = V3 = V4 = 3.5 V. (This status is referred to

as initial status.)

3. 1 CCT pin internal resistance (RINC)

The CCT pin internal resistance (RINC) is RINC = VDS / ICCT, ICCT is the current which flows from the CCT pin when

setting V1 = 4.7 V from the initial status.

3. 2 CDT pin internal resistance (RIND)

The CDT pin internal resistance (RIND) is RIND = VDS / ICDT, ICDT is the current which flows from the CDT pin when

setting V1 = 1.5 V from the initial status.

3. 3 CIT pin internal resistance 1 (RINI1)

The CIT pin internal resistance 1 (RINI1) is RINI1 = VDS / ICIT1, ICIT1 is the current which flows from the CIT pin when

setting VVINI = VDIOV1 max.

+ 0.05 V from the initial status.

3. 4 CIT pin internal resistance 2 (RINI2)

The CIT pin internal resistance 2 (RINI2) is RINI2 = VDS / ICIT2, ICIT2 is the current which flows from the CIT pin when

setting VVINI = VDIOV2 max

. + 0.05 V from the initial status.

3. 5 CCT pin detection voltage (VCCT)

The CCT pin detection voltage (VCCT) is the voltage at the CCT pin when the COP pin's voltage is set to "L"

(voltage VDS

× 0.1 V or less) after increasing the CCT pin's voltage gradually, after setting V1 = 4.7 V from the

initial status.

3. 6 CDT pin detection voltage (VCDT)

The CDT pin detection voltage (VCDT) is the voltage at the CDT pin when the DOP pin's voltage is set to "L"

(voltage VDS

× 0.1 V or less) after increasing the CDT pin's voltage gradually, after setting V1 = 1.5 V from the

initial status.
